Crowley, a 42-year resident of Los Altos Hills, has participated in Open Studios for 18 years, which she said is “the most consecutive years of any of the 400-plus artists participating in the three weekend venues.”

Earlier this year, Crowley’s oil painting “Ferry to Seattle” received “Best of Show” in a competition among local artists sponsored during the San Francisco Museum of Modern Art’s “Project Los Altos” exhibitions.

Crowley said she will have hundreds of matted watercolor works on display at her Treehouse Studio. She plans to demonstrate her watercolor technique both days.

Silicon Valley Open Studios is a nonprofit organization that has connected art enthusiasts with local art and artists for 28 years.

Participating artists work in a variety of visual media, including painting, watercolors, mixed media, jewelry, photography, sculpture and pottery.

“This free event enables visitors to spend quality time with the artists in a comfortable setting,” said Mel Thomsen, executive director of Silicon Valley Open Studios. “Visitors can talk with the artists, see a larger body of the artists’ work than is typically available and, in some cases, see the artists at work.”

Silicon Valley Open Studios attracts many emerging and first-time artists.
